The two got into it this a.m. when Perez posted some mocking photos of Allen's weekend in the Bahamas. While a part of Pop & Hiss wishes Lily wouldn't acknowledge such posts, the ensuing drama resulted in some procrastination-worthy back-and-forth. Indeed, even when we're not in a place to listen to Allen's spry new album, "It's Not Me, It's You," she's keeping us entertained.

When Perez egged her on, jokingly posting that he should be cast in Allen's next video, the Brit shot back with the strongest line of this mini-Twitter tussle: "oh, I'm sorry , we've already cast the jealous and bitter lonely old queen role. Next time eh ?"

The two then touched on the drastically lowering cost of digital albums, debated who was more obsessed/jealous with whom, and even brought Katy Perry's name into the scrap. Ultimately, Allen blocked Perez, and normally, seeing a pop star get into such a gossip war would distract from the music (read our review of Lily's new album here). But even on Twitter, Allen has a knack for turning life's daily sideshows into spirited theater.
